BRITNEY'S MOM MAKES SHOCKING CLAIMS AGAINST SAM

Lynne Spears says Sam Lufti drugged her pop star daughter, Britney Spears, according to legal papers released Tuesday. Lufti is accused of cutting off Britney's phone service, lying about medication and hiding Britney's dog, in a declaration filed by Lynne.

"Sam told [my friend] Jackie and me that he grinds up Britney's pills, which were on the counter and included Risperdal and Seroquel," Lynne said in the court document. "He told us that the doctor who is treating her now is trying to get her into a sleep-induced coma so that they could then give her drugs to heal her brain."

Lynne also explained that Sam "cut Britney's home phone line and removed her cell phone chargers. He yells at her. He claims to control everything."

According to Lynne, "Sam had told Britney that she was an unfit mother, a piece of trash and a whore, that she cares more about Adnan, her current boyfriend, than she cares about her kids, and that she does not deserve the kids."

As tensions between Lufti and the family escalated during an intervention, Sam allegedly said, "If you try to get rid of me, she'll be dead and I'll piss on her grave."
